"In the faculty there were Dieffenbach, the foremost surgeon of his day; Schoenlein, the great physician who had come from Zurich the same year to join, not only the teaching body, but to act as a reporting counsellor for the ministry and to serve as physician-in-ordinary to the King; Froriep, who was in charge of the Pathological Institute; Caspar, who {220} was also medical counsellor, with a seat in the special deputation for medical affairs in the ministry; but towering above them all was the intellectual figure of Johann Müller, the Professor of Physiology. He was an original genius with daring, actually engaged in winnowing the wheat of demonstrated truth from the prevailing chaff of egoistic opinion which divorced physical science from speculative philosophy. Prompted by the inspiration which he had derived in turn from Bichat and the French school, the Professor of Physiology was busily retesting in the laboratory truths previously elaborated by Haller, Whytt, Spalanzani, Cullen, Prochaska, John Hunter, the Bells, Magendie, Berzelius and Bichat himself." This is the tribute to Johann Müller, nearly fifty years after his death. That of Virchow, at his obsequies in Berlin, is even more enthusiastic. Virchow, then at the age of thirty-seven, at the height of his powers, already acknowledged the greatest of living pathologists, just recalled to Berlin to become Professor of Pathology in the University which he had left more or less in disgrace because of his political opinions, could not say too much of the teacher whom he respected and honored so highly and whose inspiration he felt stood for so much in his own career. He said: "My feeble powers have been invoked to honor this great man whom we all, representatives of the great medical family, teachers and taught, practitioners and investigators, mutually lament and whose memory is still so vividly with us. Neither cares by day nor labors by night can efface from our mind the sorrow which we feel for his loss. If the will made the deed, how gladly would I attempt the hopeless task of proper appreciation. Few have been privileged, like myself, to have this great master beside them in every stage of development. It was his hand which guided {221} my first steps as a medical student. His words proclaimed my doctorate and from that spot, whence now his cold image looks down upon us, his kindly eyes beamed warmly upon me, as I delivered my first public lecture as Privat-Docent under his deanship. And, in after years, I was the one out of the large number of his pupils who, by his own choice, was selected to sit beside him within the narrow circle of the faculty.
